Book excerpt: In the past ten years, Swedish floral designer Per Benjamin developed his own color theory. The World of Colour according to Per Benjamin is an educational-entertaining-inspirational book where his color theory is explained in text, but above all presented in a very creative, visual 'hands on' style in beautiful pictures and color charts. The photos are a mixture of studio works, outdoor pieces and bigger event designs (such as the Nobel Prize award ceremonies) and show both small and extra large arrangements. All of the pictures included illustrate how it is possible to extract color tones from a material both in theory and in practice.
